Description

Technical Field

[0001] This invention relates to the field of balloon dilation pressure pump technology, and particularly to an aortic valve balloon dilation pressure pump. Background Technology

[0002] A balloon dilation pressure pump is a device used in balloon angioplasty (Gastric Angioplasty). It mainly consists of a pressure pump and tubing connected to the balloon. The function and purpose of the balloon dilation pressure pump is to inflate and inflate the balloon. Balloon dilation pressure pumps are commonly used in the medical field for inflating and securing vascular stents, braided tubing, etc. In addition, balloon dilation pressure pumps can also be used in industrial and laboratory fields for inflating and expanding gas-sealed devices, tubing, etc.

[0003] The working principle of a balloon dilation pressure pump is to increase the pressure inside the balloon by injecting fluid into the balloon, thereby inflating the balloon and dilating blood vessels, which is used to treat narrowed or blocked blood vessels.

[0004] Balloon dilation pumps are widely used in interventional cardiology and vascular surgery. They can be used to treat heart disease, coronary artery stenosis, arteriosclerosis, and other conditions. During the procedure, doctors can precisely dilate blood vessels by controlling the balloon dilation pump.

[0005] However, the pressure pumps currently available on the market for aortic valve balloon dilation mainly control pressure by squeezing a handle component fitted outside the rack to control the state of the threaded connection between the rack and the syringe. Pressure pumps that simply use rack control have small distances between the buds on the rack, which directly results in slow rotation and pressurization, which is very time-consuming and cannot achieve rapid output of high pressure, affecting the operation. During the pressurization process, the piston rod needs to be rotated repeatedly, which can easily cause hand fatigue. Moreover, the air outlet of the syringe is at the top, which makes it inconvenient to push the top of the syringe onto the table to complete the pressure output with a single press when ultra-high pressure is required. Summary of the Invention

[0006] The main objective of this invention is to propose an aortic valve balloon dilation pressure pump, which aims to solve the technical problem that existing pressure pumps used for aortic valve balloon dilation cannot achieve rapid output of high pressure, thus affecting the performance of the surgery.

An air outlet is protruding from the side wall of the front end of the syringe. The pressure...

The upper end of the locking member has a first through hole recessed on each of its two side walls. The short shaft is rotatably embedded in the first through hole. The second receiving groove has a second through hole recessed on each of its two side walls. The lower end of the connecting plate has a... A third through hole is provided. The rotating shaft is sequentially disposed in the second through hole, the upper end of the through groove, and the third through hole. The inner peripheral wall of the upper end of the through groove is provided with a wedge-shaped surface, and the rotating shaft can slide along the wedge-shaped surface. By rotating the locking member to the right, the external thread of the piston rod engages with the internal thread of the through groove, locking the relative position between the piston rod and the syringe. By rotating the locking member to the left, the external thread of the piston rod separates from the internal thread of the through groove, unlocking the piston rod. One end of the braided hose is connected to the air outlet.

[0008] Optionally, an elastic limiting plate is provided on the front end wall and the rear end wall of the upper end of the first receiving groove, respectively. The elastic limiting plate can be abutted against the rear end wall of the locking member, and the elastic limiting plate is used to limit the position of the locking member.

[0009] Optionally, a first limiting plate is provided on the left and right inner sidewalls of the upper end of the first receiving groove, and a second limiting plate is provided on the left and right outer sidewalls of the upper end of the sleeve, with the lower end wall of the first limiting plate abutting against the upper end wall of the second limiting plate.

[0010] Optionally, the rear end of the piston is recessed with a insertion groove, and the front end of the piston rod is provided with an insertion part, which is detachably embedded in the insertion groove.

[0011] Optionally, the inner peripheral wall of the insertion groove is recessed with a plurality of first limiting grooves along the circumferential direction, and the outer peripheral wall of the insertion part is provided with a plurality of limiting flanges, the limiting flanges being detachably embedded in the first limiting grooves.

[0012] Optionally, multiple sealing rings are provided, and multiple second limiting grooves are recessed along the circumferential direction on the outer peripheral wall of the piston, and the sealing rings are detachably embedded in the second limiting grooves respectively.

[0013] Optionally, a handle lug is provided on each of the two side walls of the rear end portion of the syringe.

[0014] Optionally, the syringe has a capacity of 50mL-70mL and a pressure of 15PSI-40PSI.

[0015] Optionally, the braided hose includes a polyurethane layer and a nylon filament layer, wherein the polyurethane layer is provided in two layers and the nylon filament layer is disposed between the two polyurethane layers.

[0016] The technical solution of this invention has the following beneficial effects:

[0017] 1. The technical solution of the present invention includes a first receiving groove recessed in the outer peripheral wall of the rear end of the syringe, into which the sleeve is detachably embedded. A second receiving groove is recessed in the upper end of the sleeve. The lower end of the locking member is rotatably embedded in the second receiving groove. A through groove is recessed in the front end wall of the lower end of the locking member. An internal thread is provided on the inner bottom wall of the through groove. An external thread is provided on the outer peripheral wall of the piston rod. The piston rod is movably inserted through the through groove, and the external thread of the piston rod can be screwed onto the internal thread of the through groove. The upper end of the locking member... The outer side wall of the locking element has a recessed opening groove. A short shaft protrudes from each of the two side walls of the upper end of the connecting plate. A first through hole is recessed from each of the two side walls of the upper end of the locking element, and the short shaft is rotatably embedded in each of the first through holes. A second through hole is recessed from each of the two side walls of the second receiving groove. A third through hole is recessed from the side wall of the lower end of the connecting plate. A rotating shaft passes sequentially through the second through hole, the upper end of the through groove, and the third through hole. The inner circumferential wall of the upper end of the through groove has a wedge-shaped surface, and the rotating shaft can slide along the wedge-shaped surface. By rotating the locking element to the right... The piston rod's external thread engages with the through groove's internal thread, locking the relative position between the piston rod and the syringe. Turning the locking mechanism to the left disengages the piston rod's external thread from the through groove's internal thread, unlocking the piston rod. In practical use, the piston rod can be quickly pressed forward to a certain position, then the locking mechanism can be turned to the right to engage the piston rod's external thread with the through groove's internal thread, thus locking the relative position between the piston rod and the syringe and preventing the piston rod from retracting, which could cause pressure output failure and affect the surgery. The pressure value output by the pressure pump can be displayed visually via a pressure gauge. When the output pressure is insufficient, the piston rod can be manually moved forward by turning the knob to precisely adjust and control the output pressure, making the pressure output of the pressure pump controllable. This makes the pressure output and adjustment control of the pressure pump more convenient and faster, and it requires no electricity. The pressure output has the advantages of flexibility and controllability. During surgery, the doctor can control the balloon dilation pressure pump to achieve precise aortic valve balloon dilation, ensuring the safety and effectiveness of the surgery by controlling the pressure.

[0018] 2. By placing the air outlet on the side wall of the front end of the syringe, the pressure pump can push the top of the syringe onto the table when outputting ultra-high pressure, so that ultra-high pressure can be output with one press without pressing the braided tubing and causing blockage. This makes it more convenient for the pressure pump to output high pressure. Attached Figure Description

[0031] This invention proposes an aortic valve balloon dilation pressure pump.

[0032] like Figures 1 to 7 As shown, in one embodiment of the present invention, the aortic valve balloon dilation pressure pump includes a syringe 101, a piston rod 102, a piston 103, a sealing ring 104, a pressure gauge 105, a knob 106, a sleeve 107, a locking member 108, a connecting plate 109, a rotating shaft (not shown), and a braided hose 200. The front end of the piston rod 102 is slidably disposed within the syringe 101. The piston 103 is slidably disposed within the syringe 101. The sealing ring 104 is clamped onto the outer peripheral wall of the piston 103, and the outer peripheral wall of the sealing ring 104 slidably abuts against the inner peripheral wall of the syringe 101. An air outlet 101 protrudes from the side wall of the front end of the syringe 101. 1. A pressure gauge 105 is detachably mounted on the side wall of the front end of the syringe 101, and the pressure gauge 105 is connected to the syringe 101. A knob 105 is located at the rear end of the piston rod. A first receiving groove 1012 is recessed in the outer peripheral wall of the rear end of the syringe 101. A sleeve 107 is detachably embedded in the first receiving groove 1012. A second receiving groove 1071 is recessed in the upper end of the sleeve 107. The lower end of the locking member 108 is rotatably embedded in the second receiving groove 1071. A through groove 1081 is recessed in the front wall of the lower end of the locking member 108. An internal thread 1082 is provided on the inner bottom wall of the through groove 1081. The piston rod 102 is... The peripheral wall is provided with external threads, and the piston rod 102 is movably inserted into the through groove 1081. The external thread of the piston rod 102 can be screwed onto the internal thread 1082 of the through groove 1081. The outer side wall of the upper end of the locking member 108 is recessed with an opening groove 1083. The two side walls of the upper end of the connecting plate 109 are respectively provided with a short shaft 1091. The two side walls of the upper end of the locking member 108 are respectively recessed with a first through hole 1084. The short shaft 1091 is rotatably embedded in the first through hole 1084. The two side walls of the second receiving groove 1071 are respectively recessed with a second through hole 1072. The side wall of the lower end of the connecting plate 109 is recessed with a third through hole 1072. 092, the rotating shaft is sequentially installed in the second through hole 1072, the upper end of the through groove 1081 and the third through hole 1092. The inner peripheral wall of the upper end of the through groove 1081 is provided with a wedge-shaped surface 1085, and the rotating shaft can slide along the wedge-shaped surface 1085. By rotating the locking member 108 to the right, the external thread of the piston rod 102 engages with the internal thread 1082 of the through groove 1081, locking the relative position between the piston rod 102 and the syringe 101. By rotating the locking member 108 to the left, the external thread of the piston rod 102 separates from the internal thread 1082 of the through groove 1081, unlocking the piston rod 102. One end of the braided hose 200 is connected to the air outlet 1011.

[0033] Specifically, an elastic limiting plate 1013 is provided on the front end wall and the rear end wall of the upper end of the first receiving groove 1012. The elastic limiting plate 1013 can be abutted against the rear end wall of the locking member 108. The elastic limiting plate 1013 is used to limit the position of the locking member 108. When the locking member is pried to the right to lock the piston rod, the position of the locking member can be fixed by the elastic limiting plate, so that the piston rod can be locked securely and stably, stabilize the output pressure, and prevent the locking member from unlocking automatically.

[0034] Specifically, a first limiting plate 1014 is protruding from the left and right inner sidewalls of the upper end of the first receiving groove 1012, and a second limiting plate 1073 is protruding from the left and right outer sidewalls of the upper end of the sleeve 107. The lower end wall of the first limiting plate 1014 abuts against the upper end wall of the second limiting plate 1073, which serves to limit the sleeve and prevent it from coming loose from the first receiving groove. At the same time, it also serves to stop rotation and prevent the sleeve from rotating on its own, which would affect the locking of the piston rod, cause pressure output failure, and affect the operation.

[0035] Specifically, the rear end of the piston 103 is recessed with a insertion groove 1031, and the front end of the piston rod 102 is provided with an insertion part 1021. The insertion part 1021 is detachably embedded in the insertion groove 1031, making the installation between the piston and the piston rod more convenient and quick.

[0036] Specifically, the inner peripheral wall of the insertion groove 1031 is recessed with a plurality of first limiting grooves 1032 along the circumferential direction, and the outer peripheral wall of the insertion part 1021 is provided with a plurality of limiting flanges 1022. The limiting flanges 1022 are detachably embedded in the first limiting grooves 1032 to limit the piston and prevent it from coming off the piston rod.

[0037] Specifically, multiple sealing rings 104 are provided, and multiple second limiting grooves 1033 are recessed along the circumferential direction on the outer peripheral wall of the piston 103. The sealing rings 104 are detachably embedded in the second limiting grooves 1033, thereby achieving a reliable sealing effect.

[0038] Specifically, the two side walls of the rear end of the syringe 102 are respectively provided with a handle lug 1015 to facilitate pressing the piston rod to output pressure.

[0039] Specifically, the syringe 101 has a capacity of 50mL-70mL.

[0040] Specifically, a lever 1086 protrudes from the rear end wall of the upper end of the locking member 108, which facilitates moving the locking member left and right to lock the piston rod and unlock it.

[0041] Specifically, a V-shaped groove 1093 is recessed in the upper wall of the connecting plate 109. The V-shaped groove allows the connecting plate to extend and retract, making the installation of the connecting plate more convenient.

[0042] Specifically, the inner diameter of the syringe is 21.3 mm, the outer diameter of the syringe is 25.5 mm, the length of the syringe is 260.5 mm, the outer diameter of the piston rod is 12.2 mm, the length of the piston rod is 245.7 mm, the outer diameter of the piston is 21 mm, and the length of the piston is 19 mm.

[0043] Specifically, the braided hose 200 includes a polyurethane layer and a nylon filament layer. The polyurethane layer has two layers, and the nylon filament layer is placed between the two polyurethane layers. The nylon filament layer plays a reinforcing role, ensuring that the braided hose is resistant to high pressure, elastic, not too stiff, and has high transparency.

[0044] In practical use, the piston rod can be quickly pressed forward to a certain position, and then the locking device can be turned to the right to engage the external thread of the piston rod with the internal thread of the through groove, thereby locking the relative position between the piston rod and the syringe and preventing the piston rod from retracting, which would cause the pressure output to fail and affect the operation. The pressure value output by the pressure pump can be displayed intuitively through the pressure gauge. When the output pressure is insufficient, the piston rod can be advanced by manually turning the knob to precisely adjust and control the output pressure, making the pressure output of the pressure pump controllable. This makes the pressure output and pressure adjustment control operation of the pressure pump more convenient and quick, and it does not require electric drive. The pressure output has the advantages of flexibility and controllability. During the operation, the doctor can control the balloon dilation pressure pump to achieve precise aortic valve balloon dilation. By controlling the pressure, the safety and effectiveness of the operation can be ensured. When pressurizing, the top of the syringe can be pushed against the table to achieve ultra-high pressure output with a single press, making it more convenient for the pressure pump to output high pressure.

[0045] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
